DETROIT -- Investigators canvassed the area where 19-year-old Renisha McBride was fatally shot, knocking on 80-100 doors trying to gain additional information, but found just one witness.

"We would want to know wherever she went," said James Bivens Jr., chief of the criminal investigations division of the Wayne County Prosecutor's Office, who testified Tuesday in the trial of Theodore Wafer, the 55-year-old man charged with killing McBride.

She was involved in an accident just before 1 a.m. in Detroit. According to prior testimony, McBride crashed into a parked vehicle after drinking vodka and smoking marijuana.

Her whereabouts from shortly after the accident to the time she ended up on Wafer's porch in Dearborn Heights, Michigan around 4:30 a.m. -- more than three hours later -- remain unknown.

Bivens testified that he did not find anyone who saw McBride after the car crash.

The person investigators talked with, Ray Murad, testified Monday that he heard a sound - like a tree hitting his car - early Nov. 2 and went outside on the windy, raining morning to check it out, then heard a shot 10-15 minutes after returning inside.

"I didn't see anything," Murad said Monday. "I went outside but not all the way to the street."

Police were at his neighbor's house minutes later, he said. Authorities have said Wafer shot McBride in the face with a 12-gauge shotgun around 4:40 a.m. on Nov. 2.

Wafer faces charges of second-degree murder, manslaughter and using a firearm in a felony in the death of McBride, who was unarmed.

Prosecutors contend Wafer created a situation where death or great bodily harm was likely to occur and that his actions were "unnecessary, unjustified and unreasonable" and said he had other options the night McBride showed up at his house.

Defense attorneys, who argue Wafer shot McBride in self-defense, also have questioned how police investigated the young woman's death, saying the probe was "incomplete and inadequate and evidence was lost."

Cheryl Carpenter, Wafer's lawyer, continued that line of questioning Tuesday, asking Bivens if anyone went to a BP gas station near where the crash happened, which is 0.4 miles from Wafer's home.

Bivens said he did not go and doesn't recall whether he directed anyone to go to the gas station. He and six other detectives canvassed the area, he testified.

Bivens also said there is no evidence that Wafer and McBride knew each other.

Both sides cited case law supporting their arguments - the defense that they should be able to see the investigator's hand-written notes, prosecutors that the defense shouldn't get access to those notes. Wayne County Circuit Judge Dana Hathaway ruled those notes don't have to be turned over.

Michigan State Police Shawn Kolonich, a forensic firearms examiner identified as an expert in firearms and tool mark identification, tested the Mossberg, model 500A shotgun, used by Wafer.

He is the 21st witness to testify in four days for the prosecution. The medical examiner who performed the autopsy on McBride has yet to take the stand, and the defense plans to call a forensic pathologist, they've said during court.
